Abstract

The invention provides a bio-signal quality assessment apparatus and a bio-signal quality assessment method. The bio-signal quality assessment apparatus may include: a bio-signal obtainer configured to obtain a bio-signal; and a processor configured to extract periodic signals from the obtained bio-signal, and determine a signal quality index based on at least one of similarity between the extracted periodic signals and signal variability of the obtained bio-signal.

Description

[0001] This application claims Korean Patent Application No. 10-2017-0164562 filed with the Korean Intellectual Property Office on December 1, 2017 and Korean Patent Application No. 10-2018-0076515 filed with the Korean Intellectual Property Office on July 2, 2018 The priority of the patent application, the disclosure of said Korean patent application is hereby incorporated in its entirety. technical field [0002] Apparatuses and methods consistent with exemplary embodiments relate to evaluating the quality of biological signals acquired from a subject. Background technique [0003] When measuring or estimating biological information from a biological signal, the quality of the measured biological signal affects the reliability of the measured or estimated biological information. [0004] There is a way to evaluate based on the signal-to-noise ratio (SNR) by calculating the frequency spectrum of the biological signal, calculating the power (power) in the frequency range of ...
